There is provided a floating nut which opportunity of application can be expanded by increasing the floating amount of the floating nut. The clearance between the spline of an outer circumferential surface of a nut and a spline opening of a retainer is freely set on the condition that the outside diameter d of a flange 6 of the nut and the outside diameter d of a stop ring are larger than the diameter of a spline opening of the retainer The applications of the floating nut can be extended by determining the clearance between the spline of the outer circumferential surface of the nut and the spline opening of the retainer according to the required floating amount.

Floating nut

A plug-type sealing assembly for hermetically closing a filler hole 24 of a lid 19 of a container 20, comprises: a plug 1 having a rod portion 3 in an upper part of which a large-diameter head portion 2 is formed, the rod portion 3 having a male screw 5 in its outer peripheral surface; and, a sleeve 8 provided with an axial through-hole together with a countersunk head portion 10 and a slit skirt portion 11 extending downward from a lower end of said countersunk head portion 10. In the through-hole, a female screw 15a, 15b is formed. In the container 20: through the filler hole 24 a sealant 23 is supplied between joint portions of the container 20 so that the container 20 is hermetically sealed; and, the sealing assembly is easily removed from the filler hole 24 to ensure that the sealant 23 is supplemented or replaced with a new one through the filler hole 24 in an easy and a safety manner, and easily mounted again in the filler hole 24 after completion of such supplementing or replacing operation of the sealant 23, by threadably engaging the male screw 5 of the plug 1 with and disengaging from the female screw 15a, 15b of the sleeve 8.
